Abstract
The invention discloses a disperse fluorescent dye, a preparation method and application thereof. The disperse fluorescent dye is a compound with a structure shown as the following general formula (I). The disperse fluorescent dye provided by the invention has the advantages of simple preparation process, good fluorescent effect, bright color, excellent application performance and convenient use, and has strong applicability.
Description
Technical field
The present invention relates to a kind of fluorescence dye, particularly relate to a kind of dispersion fluorescence dye preparation and application.
Background technology
The visual effect of fluorescence dye had both comprised the color to visible light selective absorption rear generation, comprised again the fluorescence that they emit.It belongs to a kind of Functional dye, has both had the tinctorial property of conventional dyestuff, can launch fluorescence again, and the saturation ratio of fabric and vividness are improved.Benzimidizole derivatives can be launched stronger fluorescence in organic solvent and the aqueous solution, therefore people utilize the characteristic that its fluorescence quantum yield is higher, be applied to differentiate and analyze organic compound, medicine, and for the fluorescent mark of biomacromolecule.Have in the market DISPERSE YELLOW 8GFF and the cationic yellow X-10GFF of benzimidizole derivatives structure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dispersion fluorescence dye of vinylbenzene benzimidazole structure, can dye to polyster fibre, yarn and fabric, is used for preparing fluorescent fiber, yarn and fabric.Particularly, the invention provides the compound of lower formula I:
（Ⅰ）
This compou nd synthesis method comprises the steps:
In propyl carbinol, adding N-Ethyl-2-Methyl benzoglyoxaline and N-ethyl-N-cyanoethyl-4-aminobenzaldehyde is raw material, acetic anhydride is catalyzer, in molar ratio, N-Ethyl-2-Methyl benzoglyoxaline, N-ethyl-N-cyanoethyl-4-aminobenzaldehyde and acetic anhydride 1:1:0.1～1.2:1:0.1, in temperature, be to react 10～12 hours under the condition of 100～105 ℃, through column chromatography for separation, obtain compound (I).
This dyestuff to dyeing terylene technique is: compound (I) consumption 0.05～10% (o.w.f, to fabric weight), bath raio 1:20～1:100, vinegar acid for adjusting pH value 4～5, room temperature enters to dye, and 2 ℃/min is warmed up to 120～135 ℃, insulation 40～60min, dyes completely, washes, soaps, washes.
Accompanying drawing explanation
Fig. 1 is for disperseing the structure iron of fluorescence dye.
Embodiment
To the present invention, disperse structure, preparation method and the application of fluorescence dye to be illustrated above, below will be by embodiment to work further instruction of the present invention.
embodiment 1:
The present embodiment provides the preparation method of formula I compound:
Concrete preparation method is as follows:
In propyl carbinol, adding N-Ethyl-2-Methyl benzoglyoxaline 8g and N-ethyl-N-cyanoethyl-4-aminobenzaldehyde 10g is raw material, 0.5g acetic anhydride is catalyzer, in temperature, be to react 12 hours under the condition of 100 ℃, through column chromatography for separation (silicagel column, sherwood oil: ethyl acetate=2:1), obtain compound (I).
embodiment 2:
The present embodiment provides the dyeing process of formula I compound to polyester piece good:
Concrete dyeing process is as follows:
Compound (I) consumption 2.0% (o.w.f, to fabric weight), bath raio 1:50, vinegar acid for adjusting pH value 5, room temperature enters to dye, and 2 ℃/min is warmed up to 130 ℃, and insulation 60min, dyes completely, washes, soaps, washes.Dye uptake 96.4%.
The prepared dispersion fluorescence dye application performance of the present invention is as follows:
